Abstract (en)
[origin: EP3677547A1] The present invention relates to a method for recycling supercritical waste liquid generated during a process of producing a silica aerogel blanket, and a method for producing a silica aerogel blanket reusing supercritical waste liquid recycled thereby. More particularly, the present invention provides a method for recycling supercritical waste liquid and a method for producing a silica aerogel blanket capable of reducing the production costs and preventing the deterioration in thermal insulation performance of a silica aerogel blanket by adding a metal salt to the supercritical waste liquid by the recycling method.
